2M
The S connector module allows you to operate an OpenCom 130 / 150 on a primary
2M
rate access. This access provides up to 30 voice channels. You can also use the S
port to network two systems, e.g. in order to use the OpenCom 130 / 150 as a sub-
sidiary system or DECT server.

If an S connector module is installed in the OpenCom 130 / 150, please consider the
2M
